INSTALL.md

Installation and running the RPi-LoRa-Gateway

Install needed packages

sudo apt install python3 python3-rpi.gpio python3-spidev aprx screen git python3-pil python3-smbus

Checkout the code

Enter following commands:

cd
git clone https://github.com/tomelec/RPi-LoRa-KISS-TNC.git
cd RPi-LoRa-KISS-TNC
git clone https://github.com/mayeranalytics/pySX127x.git

to change into homedirectory and then checkout the code and the LoRa Chip-Driver in the right directory.

Configuration

Afterwards configure as following:

Edit aprx/aprx.conf.lora-aprs file

Type:

cd
cd RPi-LoRa-KISS-TNC
sudo cp aprx/aprx.conf.lora-aprs /etc/aprx.conf
pico -w /etc/aprx.conf

to copy and then open the config file.

The most important settings are:

• mycall
  Your call with an apropriate SSID suffix
  Paper on SSID's from aprs.org
• myloc
  NMEA lat/lon form:

lat ddmm.mmN lon dddmm.mmE

Example:

lat 4812.52N lon 01622.39E

(simplest way to find the right coordinats for this? Go to aprs.fi on your location right-click and choose "Add marker" then click on the marker and you should see your coordinates in the NMEA style - enter this infos without any symbols into the config file as seen in the example above)

• passcode
  see see here to generate appropiate setting
• server
  either leave the default server or if you're connected to Hamnet as well insert an APRSIS Server within the hamnet - a List of Aprs Hamnet servers can be found in the OEVSV Wiki)

to save and close the file do: Strg + x -> Y -> Enter

Edit driver config file

Type

pico -w pySX127x/SX127x/board_config.py

change in line 36 from

DIO0 = 22  # RaspPi GPIO 22
DIO0 = 5   # RaspPi GPIO 5

to fix the SPI connection #todo how can we config this from outside?

Start the LoRa KISS TNC and aprx server instance

python3 Start_lora-tnc.py &
sudo aprx

Stop the server's

sudo killall aprx python3
